INY 'ISIBLE LOCK 39K l/LETA'JL Application filed April 20, 1921.

To all whom it may concern:

Be it known that l, LEON SPIRO, a citizen of the United States, residingat Everett, in the county of Snohomish and State of \Vashington, haveinvented certain new and useful Improvements in Invisible Looks forMetal Beds, oi which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to an r metal beds, and the object of the invetion is the construction of the legs of a bed or couch, or the like,which embody means for efiiciently locking the side irons or rails of abed to the leg or leg structure.

With this and other objects in view, my invention comprises certainnovel combinations, constructions and arrangements parts as will behereinafter described, illus trated in the accompanying drawings, andmore particularly pointed out in the appended claims.

In the drawings:

invisible lock Figure 1 is a view partly in elevation and partl insection of a leg structure corn struc ed in accordance with the presentinvention, while Figure 2 is a section taken on line 2-42,

Figure 3 is a View, in elevation, of the cur:- iliary section of the legstructure.

Figure l is a fragmentary, perspective view of one of the angle irons orrails metal bed.

Figure 5 is a fragmentary View, in eleven tion, of an embodiment of theprimary section of the leg structure, while Figure 6 is a fragmentary,perspect view of another embodiment of the iron or rail of a metal bed.

Referring to the drawi gs by numerals, 1 designates the primary hol owsect-ion leg structure, it being understood that in the construction ofa bed or couch, or e like, there are four leg structures used b i onlynecessary to illustrate desc ibe orstrnctu? as all used in theconstructio of a bed are duplicates. ltotatably mounted within theprimary section 1 is an at'ni section 2; the an iliary section 52, likeprimary section l, is hollow and preferaoiy cylindrical in s (Fig. 2}.On the lower end of the auxiliary section 2 is an ornamental flange 3,against which the lower end of the primary section 1 rests. grippingSpecification of Letters Eatent.

flange 3 and turning same, the auxiliary section will be turned orrotated within the primary section 1. A. suitable caster at is attachedto the auxiliary section 2 and supports the primary section 1.

The primary section 1 is provided with a vert'ically-extcnding slot 5,which is sufficiently wide to allow the catch 6 on the angle iron orrail 7 to enter the primary section, and extend through the taperingopening 8 formed in the side of the auxiliary section 2; this opening 8registers with the vertical slot The bottom edge 9 of the opening 8 ison the same horizontal plane with the lower end 01": the slot 5 so thatthe lower edge of the catch 6 rests on the lower edges or bottoms of theslot and the opening 8, Fig. 1. The top or upper end 10 of the opening 8(Fig. 3) is inclined from one side to the other side of the opening, sothat the catch 6 can enter the highest end of the opening 8 and, then,by turning the auxiliary section 2, the upper edge 10 of the openingwill ride through the slot 10 of the angle rail 7 until the lowestportion of the upper edge 10 of opening 8 is resting snugly in the slot10, as seen in Fig. 1, thereby securing and fastening the angle iron 7against displacement oil" the primary and auxiliary sections 1 and 2,respectively.

ln'the embodiment shown in Figs. 5 and 6, the same principal is involvedexcept that the primary section 1 is provided with a pair of slots 5*,and the rail 7* is provided with pair of catches 6, adapted to enterslots 5 and be secured therein by an auxiliary section 2, ashereinbefore described.

While I have described the preferred em bodiments oi? my invention, andhave illus trated the same in the accompanying drawings, certain minorchanges or alterations may appear to one skilled in the art to whichthis invention relates, during the extensive manufacture o1 the same,and, I, therefore, reserve the right to make such alterations or changesas shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the class described, the combination of a primaryhollow section, an curriliary hollow section within the primary hollowsection and supporting the same, said y auxiliary sections provided hregistering slots or openings, and a rail provided with a catch adaptedto enter registering slots or openings and be locked upon said sectionswhen the auxiliary section is slightly rotated within and independentlyof the primary section.

2. In a device of the class described, the combination of an auxiliarysection provided at its lower end with a flange, said auxiliary sectionhaving a large opening formed in its side, said opening having ahorizontal straight lower edge and an inclined upper edge producing awide end and a narrow end of said opening, a primary section over saidauxiliary section and resting at its lower end upon said flange, saidprimary section provided with a vertically-extending slot registeringwith the opening of said auxiliary section, a rail provided with acatch, and a slot on the rail between the rail and the catch, said catchadapted to extend through the slot of the primary section and throughthe opening of the auxil- I iary section and rest upon the bottom edges7 signature.
